Y When coarse material is being handled the interlocking of the parts above `discussed is ordinarily sufficient to prevent anylcakage between the iixedpand movable chute gate and other parts. It frequently happens, however, when fine material or material that flows very freely is being handled that as the ma terlal piles up in the chute and even as it travels along the chute it lows outinto the spaces between 4the fixed and moving parts,

causes binding and interferes withv smooth f opertion. Y I provide, therefore, packing means to prevent such action. This packing means or sealing means takes the form of an arcuate wear or packing strip D, held in Vplace by means of the flush headbolts D1 and nuts D? on the curved ends of the side plates H B?. Engaging these ypacking strips D are packing or sealing strips D3 mounted on the side plates Ba Btconcentric with the strips'l D and adapted to travel thercalong when "the combined chute and gate rotates. These Strips D3 are anchored atone end by lmeans of holding` bolts D, are yieldingly pressed against the strip D by means of springsDi in sockets Da and are provided'with'tension adjusting screws D7; ln that part of the struc,- ture where thestrips D3 are adjacent the gate yB they are held in position between it and.

' 3a acurved flange D8. This flange Ds extends -`around to the top of the pivoted chute and thereis an additional flange D kextending upwardly from the upper terminus of the gate t0 the top of the pivoted chute, so that the 40 Vpacking or sealing strip D3 while generally constrained, is given `a certain `freedom of motionradially to preventibindingzand vto permit itto properly position itself withl rei `spect tothe fixed strip `D, and also the strip i-jD, and above the gate-thestripsDspandiD zprotect the adjustable tension springs and the space between the floatingk packing strip D3 'and the wall B* `and `assist in ypreventing escape of the material into the space between wat/beside plates'B2 and Bs-or B. f

It will be evident that whileil have shown my drawings an operative device, still many changesmight be made both in size, ""'fshape and arrangement'offparts without 1de- Vparting materially from the .spirit of my invention andy IY wish therefore that my drawregardedas in a sensediagrammatic. i fferring to Figures 7 and "8, it Awill be noted that instead of the spring held engag- 'ingsegmental rings, I provide two flexible A -`AV,strips F held cna fflange F1 together with a single'lllexible strip F2 traveling between them. Under some conditions this would be a thoroughly satisfactory means ofV packing t5 the device though would notbe as strong and would be more appropriate for use in connection with material lighter than the material ordinarily used.
